REF1930AIDDCR

Overview

The REF1930AIDDCR is a dual-output voltage reference from Texas Instruments, providing fixed outputs of 3 V and 1.5 V (Vref/2). It operates within an input voltage range of 3.3 V to 6 V. The device features an initial accuracy of 0.1% and a temperature coefficient of 25 ppm/C. Maximum shunt current is 20 mA, with a supply current of 360 uA. It functions in temperatures from -40°C to +125°C and uses a SOT-23-Thin-5 package.

Feature Summary

• Dual-output architecture delivering both Vref and Vref/2 simultaneously
• Low-drift performance with 25 ppm/C temperature coefficient
• High initial accuracy of 0.1%
• Low power consumption suitable for battery-operated systems

Applications

• Data acquisition systems requiring precise dual rails
• Industrial process control instrumentation
• Medical equipment signal conditioning
• Portable test and measurement devices

Procurement Notes

Verify the specific suffix 'CR' indicates tape-and-reel packaging versus 'CT' cut tape. Confirm RoHS compliance status through official TI documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the operating temperature range meets system specifications.

Selection Notes

Select this component when dual output voltages are required without external resistors. Compare against REF1925 or REF2033 if different voltage levels or lower drift are needed. Verify input voltage compatibility with the 3.3 V minimum requirement. Consider package size constraints for SOT-23-Thin-5 footprint.

Part Context

Part of the REF19xx family of low-drift, low-power voltage references. Designed for applications needing stable reference voltages in compact spaces. Manufactured by Texas Instruments as part of their PMIC portfolio.

Replacement Considerations

REF1930AIDDCT offers identical electrical characteristics but in cut-tape packaging. REF1925AIDDCR provides 2.5 V and 1.25 V outputs instead. REF2033AIDDCR offers lower drift at 8 ppm/C but different output voltages.
